  1. From the result we get the following conclusion : for narrow - band signal, the effect of the method based on fft is best. for wide - band signal, when snr is up to certain degree ( higher than - 7db or so ), the curves of square error of modified methods are more obvious and closer to crb. for an echo composed of more than one frequency or direction, space - frequency distribution could show more direct information of frequency and direction, which is more advantaged to make precise judge and estimation for doa of echo

    從估計結果發現,對于窄帶回波信號,基於fft的方法估計性能大大優于其他方法;對于寬帶回波信號,在信噪比達到一定程度(高於約- 7db )時,補償后的幾種估計法的性能改善均比較明顯,誤差曲線越來越接近crb曲線;對于回波存在多頻率多方位的間?頻率分布圖能提供較為直觀的頻率及方位信息,因此應用間?頻率估計法來進行方位估計,更有利於進一步對回波的具體方位進行準確和估計。
  2. For video codec, after analyzing and researching the newest standard h. 264, an efficiency algorithm was proposed in this paper using self - feature, spatial correlation and temporal correlation to judge the encoding mode of one macro - block. through this method, the best prediction mode can be obtain before encoding, then, the coding time can be reduced dramatically with a little expense of bit - rate. for video transmission, in this paper, a transmit method was proposed using tcp / ip protocol under the environment of local networks

    首先,在分析及研究最新的視頻編碼標準h . 264的基礎上,利用宏塊自身的特點和其時間、間的相關性來宏塊應該採用的編碼模式,從而提前得到該宏塊的最佳編碼模式,新方法有效地克服了原標準演算法窮舉式的復雜演算法,在壓縮碼流只有少許增加的下,大幅度地提高了幀內及幀間編碼的速度。
  3. Different arrangement to space resource makes different performance of the dominant behavior value system of social 2. 1 the establish of the dominant behavior value system of social in ancient construct in ancient society, it is often unitary. in other words, the value judgments of the whole society tend to become same in some layer. the meaning of the city elements which token by the urban designer and that in people " s mind is same in that condition

    1古代城市伺系統營造的杜會主導行為價擅系統建立古代社會,由於交流與政治等方面的因素,一定社會的行為價值體系往往是一元的,也就是說,整個社會對於行為價值的在個體層面上有明顯的趨同傾向,在這種下,城市設計者所而對的城市要素所表徵的意義與人們的理解是一致的,同時,城市建設的資源及資源的運作基本上由一種力量所控制,因而城市間系統本身很容易成為社會認可的行為價值系統的直接對應物,也就是說,古代社會,城市的間系統與行為價值系統之間的關系往往能夠呈現出明確的同構特徵。
